A second type of anomalous cryoscopic behaviour is exhibited by f-butyl esters ". The benzoate and acetate both give varying / -values between 3 and 4, and by extrapolating the value for f-butyl benzoate to zero time Kuhn1" obtained a value close to 3.0. This he interpreted as evidence for alkyl-oxygen cleavage, and the formation of the f-butyl cation, viz-... 

Evidence for the Bac2 mechanism has come from isotopic labeling studies. Hydrolysis of ethyl, isopropyl, or f-butyl benzoate labeled with...
